The US, Japan and Europe Lighting manufacturers led the establishment of the industry group "Zhaga Consortium", in order to easily design LED lighting products. Older manufacturers such as Philips Lighting BV, OSRAM GmbH, Panasonic, Toshiba and General Electric all participated in the group. It is planned to standardize an optical engine (a module composed of LEDs, drivers, and optical components) embedded in an LED lighting fixture, and submit it to the International Electrotechnical Commission (IEC) as an international standard.
After standardization, there will be more and more compatible optical engines, and it is easy for lighting fixture manufacturers to purchase parts and save the trouble of designing the optical engine alone. The cost reduction of lighting fixtures will also accelerate. For the new manufacturers involved in the LED lighting equipment business, there are also benefits to lower the barrier to entry.
In recent years, the demand for LED lighting products has become larger and larger. To take this opportunity to expand the LED lighting market, it will not cost energy for several years to achieve standardization. Meno Treffers, secretary general of Zhaga Consortium, said, "I hope that the rapid development of standards within Zhaga is the common idea of ​​all members." The standard will target high-output lighting fixtures with a beam of more than 1000 lm, first for store and outdoor lighting products, and then for standardization for office and industrial use.
Maintain a balance between competitive space and market expansion
Zhaga will standardize the smallest items specifically used to embed an optical engine into a lighting fixture. For example, the mechanical interface (shape and lamp holder, etc.), thermal interface (heat dissipation path, etc.), electrical interface (power supply, insulation, grounding, control, etc.) and optical interface (light beam, color, and light emission characteristics) will be uniformly defined when not for life. And product quality setting standards such as quality (Figure 1). Performance requirements vary by country and region, and for vendors, performance is key to product differentiation.
The internal structure of the optical engine is also not a standardized object. Although the beam standard is specified, the number of LEDs to be packaged in order to obtain a light beam, the driving method, and the like are not specified. Therefore, improving performance and reducing costs will become a competitive point for optical engine manufacturers.
The characteristics of LED brightness and luminous efficiency are still in the development stage. Every time a new LED product appeared, the lighting manufacturer had to redesign the lighting fixture. It can be said that the future standard will be a measure to fully retain the competition space of manufacturers and also effectively expand the LED lighting market.
